We are very proud that OpenAlex is free! All of the data is open, and most of our users will find our free services more than enough to meet their needs. For those who want a higher level of service (and to help support our mission!) we're also proud to offer OpenAlex Premium!
OpenAlex Premium offers faster updates, higher API limits, and priority support. Learn more at the link above. Contact us for a quote, and to get a free trial!
